<pre>Hi, my notebook thinkpad w500 has two video cards, intel / radeon. When i test
some 3d games by wine or some videos by mpv using dri_prime=1 to dynamic enable
radeon card, the game/video window always tearing, see bug report
<a class="bz_bug_link
bz_status_NEW "
title="NEW - Synchronization Artifacts with PRIME"
href="show_bug.cgi?id=76367">https://bugs.freedesktop.org/show_bug.cgi?id=76367</a>.
So i try to start second xserver directly use radeon card, command like this:
$xinit /usr/bin/openbox-session -- :1 -ac -configdir radeon
(/etc/X11/Xwrapper.config already changed to allowed_users=anybody)
I put 20-radeon.conf into /etc/X11/radeon, which is:
Section "Device"
Identifier "radeonGPU"
Driver "radeon"
BusID "PCI:1:0:0"
Option "DRI" "3"
EndSection
The basic thouhgts is default xserver using intel+radoen by dri prime that is
nice technique still needs upgrade, start second xsever just using one video
cadr(intel or radeon) as needed.
If i just put 20-intel.conf into /etc/X11/radeon (just use intel IDG), the
second xserver runs ok. Just using radeon DIS the second xserver started
without any conntected output. run 'DISPLAY=:1 xrandr' could confirm that, all
disconnected, so it's black screen on second xserver vtn, and default xserver
vt7 still ok.
Am i missing something to config second xserver using radeon DIS, or it's not
possible?</pre>
